I have thousands of rows of data in the following format (in Excel 2000):

Date Parameter Value
3/10/79 Temp 22
3/10/79 Oxygen 2.5
4/1/80 Temp 25
2/24/81 Temp 23
2/24/81 Oxygen 1.0
2/24/81 pH 7.0

I want to change it to:

Date Temp Oxygen pH
3/10/79 22 2.5
4/1/80 25
2/24/81 23 1.0 7.0

I could (and have) manually copy and transpose the values for each date.
However, as in my example, each date may have a different set of parameters.
Therefore, the resulting rows would not have the same number or even name for
resulting columns. This makes the transposition very time-consuming, as I
must transpose and then move the data into the correct columns.

I have seen formulas that will automate row-to-column conversion for set of
values that repeat (like every group of four rows in a column converts to a
row). The suggestions were like the formula below:
=OFFSET($A$1,(ROW(1:1)-1)*4,0)

Is there any way to modify this for my situation? Each group that needs to
be transposed has a unique date.

Thank you
